一 自适应点焊质量监控的研究意义 在数以万计的汽车特别是轿车生产线上,广泛采用高效的电阻点焊工艺。而对于焊点的质量检测目前尚没有十分成熟的方法,尤其对于电阻点焊这种极其短瞬焊接热过程,焊工无法直接观察也无法调节焊接参数。因此,产品开焊率较高。采用现代科学技术,特别是计算机技术的发展及其在过程控制方面的快速响应能力为汽车行业生产过程的点焊质量控制提供了可靠的甚至是具有一定智能性的监控手段。
An adaptive spot welding quality control research significance In the tens of thousands of cars, especially car production line, extensive use of efficient resistance spot welding process. At present, there is not a very mature method for the quality inspection of solder joints. Especially for the extremely short-time resistance welding, such as resistance spot welding, the welder can not directly observe and can not adjust the welding parameters. Therefore, the high rate of open welding products. The adoption of modern science and technology, especially the development of computer technology and its rapid response capability in process control, provide a reliable and even intelligent monitoring tool for spot welding quality control in the automotive industry.
